Discovering your soulmate and proposing marriage is an unforgettable moment. At Adelina Jewelry, we understand the significance of this occasion and are dedicated to helping you find an engagement ring with a diamond as unique as your partner.

This guide is designed to educate you about the various diamond shapes available so you can make the perfect choice for this special event.

Shapes of the Center Diamond in an Engagement Ring
The center diamond is the star of your engagement ring. At Adelina Jewelry, we know it’s the first stone that catches the eye when worn, which is why it’s essential to choose a diamond that reflects your personality, style, and taste. The center diamond also defines the spread, sparkle, and overall silhouette of the ring on your finger. Take your time and explore different shapes before making your decision to ensure the perfect match.

Round (Brilliant) Cut Diamonds

A round brilliant cut is the most common diamond shape and an extremely popular choice for engagement rings. It’s a timeless classic that never goes out of style because it’s specially designed to maximize brilliance.

The term “brilliant cut” comes from the extensive faceting the diamond undergoes during its crafting process. A typical round brilliant diamond has 52 facets, carefully arranged to maximize sparkle. The principle is simple: the more facets, the more brilliance. This makes the brilliant cut ideal for anyone seeking the brightest sparkle in a diamond.

Adelina Jewelry Round-Shaped Diamonds
Whether you prefer a standout solitaire, a dazzling halo, or a stunning three-stone design, we have the perfect round diamond engagement ring for you. Adelina Jewelry proudly offers a wide collection of engagement rings featuring exquisite lab-grown round diamonds.

By choosing Adelina Jewelry, you’re gifting your love a luxurious, ethically sourced, conflict-free gem. Celebrate life’s most romantic moments with a clear conscience and the radiant sparkle of our round diamonds.

What to Know When Shopping for Round Diamonds
This classic shape is always in style, but there are a few things to keep in mind. Pay close attention to clarity; round diamonds don’t hide inclusions through optical illusions like fancy cuts do. Always visually inspect your selected stone to ensure it appears flawless to the naked eye.

Choosing the right carat size is also important. Unlike fancy cuts, round diamonds are true to size. To create the appearance of a larger stone, consider a halo setting to add volume and extra sparkle.

Oval Cut Diamonds

A gleaming twist on the classic round shape, oval diamonds feature an elegant, elongated circle. They create the illusion of a larger stone, with their extended length and broad surface area making them appear bigger than other diamonds of the same carat weight.

Oval diamonds offer the same brilliance and fire as round brilliant diamonds, while giving fingers a long, slender appearance. Whether set in a solitaire or accented with halos and side stones, oval diamonds exude timeless elegance.

Adelina Jewelry Oval-Shaped Diamonds
With over 120 styles to choose from, Adelina Jewelry can help you find the oval diamond engagement ring of your dreams. Our high-quality lab-grown diamonds are available in a variety of settings, from classic solitaires to dazzling halo and three-stone designs.

What to Know When Shopping for Oval Diamonds
Oval diamonds have unique benefits, but not all are created equal. Look for a stone with an even shine and avoid diamonds with a strong bow-tie effect. The bow-tie effect occurs as dark spots across the center of some oval diamonds and can diminish sparkle. Always inspect the diamond carefully and consult one of our experts to ensure you select the perfect oval gem.

Cushion Cut Diamonds

Also known as the old mine cut, the cushion cut is a square shape with rounded corners, resembling a pillow. It’s a classic that has stood the test of time—before the round brilliant became the market favorite, the cushion cut was the most popular diamond shape for nearly 200 years.

We’re committed to providing you with the ultimate selection of lab-grown cushion cut diamonds. From eye-catching halo designs to ornate three-stone rings and timeless solitaires, Adelina Jewelry offers over 100 cushion cut diamond engagement rings for you to choose from.

What to Know When Shopping for Cushion Cut Diamonds
Cushion cut diamonds come in two distinctive styles: antique or crushed ice. An antique cushion cut diamond has precise facet patterns, while a crushed ice stone features irregular facets.

Traditionally, cushion cut diamonds were square-shaped. Modern jewelers now also offer elongated cushion cuts in rectangular shapes.

Cushion cut diamonds are highly versatile, and with so many options available, it’s important to choose a style that reflects your future spouse’s personality.

Pear Cut Diamonds

A pear-shaped diamond is a stunning variation of the brilliant cut, combining the round and marquise shapes. Also called a teardrop diamond, it has one rounded end and one pointed end, forming a symmetrical, elongated shape.

The pear cut is universally flattering, creating a long, slimming effect on the finger and often appearing larger than its actual carat weight. Its top surface is about 8% bigger than a round diamond.

What to Know When Shopping for Pear-Shaped Diamonds
Pear-shaped diamonds vary in silhouette. Slim diamonds elongate the finger, while wider bases offer a rounder look. Always choose a shape that best complements the wearer’s hand.

Emerald Cut Diamonds

Emerald cut diamonds are treasured for their elegance and elongated rectangular facets, which create a reflective “hall of mirrors” effect. Named after the emerald gemstone cut, these diamonds offer striking sophistication rather than all-over sparkle.

Princess diamonds are sophisticated and budget-efficient, using more of the rough stone. Consider a v-prong setting to protect the sharp corners from wear.

Marquise Cut Diamonds

Marquise diamonds are long, narrow, and eye-catching, creating the illusion of a larger gemstone. Also called eye-shaped or navette diamonds, their two pointed ends and convex center elongate the finger and command attention.

Our selection of marquise diamonds includes loose stones and engagement rings in show-stopping settings. Whether as a solitaire or enhanced with side stones and pavé bands, Adelina Jewelry delivers ethically sourced, breathtaking marquise diamonds.

What to Know When Shopping for Marquise Diamonds
Marquise diamonds are best appreciated for their elongated shape. Classic proportions have a length-to-width ratio of 1.75–2.15, with longer or shorter versions available for varied effects. The longer the diamond, the more it elongates the finger.

Asscher Cut Diamonds

Known for its large step facets and square shape, Asscher diamonds offer an understated yet mesmerizing shine, rather than an all-over sparkle.

The Asscher cut can be considered a condensed version of the emerald cut—roughly square with corners cut diagonally to allow more color to reflect through the diamond. Both shapes create a captivating hall-of-mirrors effect thanks to their deep step facets. This hypnotic diamond shape exudes vintage-inspired sophistication.

Introduced in 1902 by the Asscher brothers of Holland, the Asscher cut reached peak popularity during the Art Deco era of the 1920s. Brides seeking old-school glamour will fall in love with Asscher cut diamonds.

Our lab-grown Asscher diamonds are ethically sourced, conflict-free, and budget-friendly, combining beauty, sophistication, and responsibility.

What to Know When Shopping for Asscher Cut Diamonds
The flat table of Asscher diamonds provides an unobstructed view into the center of the stone, so inclusions are more noticeable. Prioritize high clarity when choosing an Asscher diamond.

Color is also crucial, as step facets accentuate any variations. Pay close attention to the color grade if you desire a pure white appearance.

Heart Cut Diamonds

Heart-shaped diamonds, crafted into the ultimate symbol of love, are perfect for romantics at heart. These diamonds sparkle with two symmetrical halves, forming a bold and romantic look. Similar to pear-shaped diamonds, they contrast pointed and curved edges, with a cleft at the top creating the iconic heart shape.

With a brilliant cut, heart-shaped diamonds deliver unmatched sparkle and fire while symbolizing love and devotion. Ideal for brides who want to express femininity and deep affection, this shape is both classic and eye-catching.

What to Know When Shopping for Heart-Shaped Diamonds
Heart-shaped diamonds come in various sizes and proportions. Traditional hearts have a length-to-width ratio of 1. Modern variations can be narrower (~1.05) for an elongated effect or shorter (~0.95) for a bolder appearance. Always consider the ratio that best flatters the wearer’s hand.
